I have a 36 inch Wega from a few years back and when I watch a DVD, or whatever, there's a black bar to the left center of the screen that is noticeable when the screen turns really dark or black. This annoys me to no end. I'd love my tv otherwise. The only way I would know how to fix this is to turn the brightness down till the blacks are so black, the bar disappears. ....But then I'd be watching DVDs and barely making people out in dark scenes. What do I do? I can get to the service menu....can I adjust anything there to solve the problem without creating another?
